@xykon Just wanted to help with bug fixing/spotting. Actually I am quite happy with the recent changes. Especially the new filesystem. So it's a good thing you released it already so we can test it properly.

OK I'll look into that. I admit I rushed this release a little bit (it's a beta after all) to get the new dual filesystem firmware released so I didn't check every possible way through the updater. Obviously the Pybytes window shouldn't show up at all when flashing from local file so hopefully this will be easy to fix.
